but that,by our frame of government, that principle has not been made one of legal obligation;

So again you can see as we're filling up our molecular orbitals, we're using the exact same principle we used to fill up atomic orbitals.

当我们填充轨道的时候可以看到，我们用的是和,填充原子轨道一样的原则。

So this, in fact, is going to be our last principle that we're going to talk about in terms of periodic trends.

实际上，这将是,我们要讨论的最后一个,周期性规律。

Our bodies have mechanisms like that, that mainly use the principle of negative feedback in order to control the parameters that are important for life within a certain range.

我们的身体有着与之类似的机制,主要依靠负反馈原理来,将与生命息息相关的指标控制在一定范围

We'll say a little bit about Beyond the Pleasure Principle, ; which is the crucial text for our purposes; but plainly apart from the influence of and the ideas borrowed from Freud, you'll find Brooks writing on what for you is pretty familiar turf.

我想花一点点时间说说《超越快乐原则》,这篇文章对于我们今天理解主题至关重要;,但是如果不看从弗洛伊德那里借来的思想和影响外，布鲁克斯所写的对于你们来说应该会很熟悉。

So if we think about, for example, this red line here, which energy state or which principle quantum number do you think that our electron started in?

我们来看看，比如这里的这个红线，它是从主量子数,等于多少的能级发出的？

And our equation for total nodes is just the principle quantum number minus 1.

总节点数等于,主量子数减１

So what we're doing is filling in those eight electrons following the Aufbau principle, so our first electron is 1s going to go in the 1 s, and then we have no other options for other orbitals that are at that same energy, 1s so we put the second electron in the 1 s as well.

它会是什么样子呢,我们正在做的是将这8个电子按照奥弗,堡原理进行填充,所以我们第一个电子将会进入，然后我们没有其他的,轨道的选择在同一个能级，所以我们把第二个电子也放入。

l So, if we're talking about a 4 p orbital, and our equation is n minus 1 minus l, the principle quantum number is 1 4, 1 is 1 -- what is l for a p orbital?

我们方程是n减去1减去，主量子数是，4，1是1，--p轨道的l是多少？,学生：
